Understanding the Working of Car Radiator

working of car radiator

Automotive car radiator is indispensable to the functioning of your car. It is pretty much the heart of your car and hence must not be overlooked. It helps dissipate the immense heat into the air and allows the car to run at nominal temperature. According to automotive radiator manufacturers, if there is a problem with your car radiator it will give rise to many other problems in your car, SUV or truck.

Let’s first understand the basic functioning of your automotive radiator.

The radiator can be located at the front of your car or in the engine’s bay of your truck. The radiator attaches to the radiator core support which is a large metal frame. Attached by a pair of brackets the radiator rests on a set of rubber bushings at the bottom. There are a number of tubes in the radiator in which coolant flows. The tubes can be seen between two tanks that hold the coolant at the inlet and outlet. Fins are attached to these tubes in the radiator core which help radiate heat into the air.

How does cooling process begin?

Water pump sends the coolant to the engine and that’s how cooling process begins. The coolant then goes around the cylinders and the heat produced due to the combustion and friction in the engine is picked. The coolant heats up due to this and enters the radiator through the upper-hose which then runs through the radiator tubes which takes on the entire heat.

Materials Used

Car radiator suppliers say that radiators are made out of a number of materials and each of them offer their own set of advantages and disadvantages.

  • Aluminum

A shift towards aluminum radiators has been seen in the past few years. It is way lighter than other materials such as copper or brass. Since it light in weight, it results in a fuel efficient and lighter radiator. It is also considered good at heat transfer. It may interest you to know that aluminum is the 4th most conductive material after silver, copper and gold.

  • Copper or brass

Copper, which is considered the second best material to conduct heat has been used for making radiators since ages. Copper tanks were quite efficacious at cooling but were heavy. One of the problems with copper is that it corrodes quite easily, but this problem can be fixed by painting. Tanks made of brass would be joined to copper tubes using lead solder.

  • Plastic

Plastic is quite light in weight and is used in radiators. Fins and tubes are made of metal, but tanks are made of plastic. One of the biggest problems with plastic is that it cannot withstand heat as metals can. It contracts and expands with cooling and heating and that’s why it doesn’t make for a good material for tanks.
